Abstract：Nano-sized TiO2 thin films were prepared on the glass by electrophoresis. Photo-catalytic experiments were carried out using the films sintered at high temperature. The morphology and structure of ul trafine TiO2 particles were analyzed by XRD，SEM，DTA and EDS measurements. The experimental results show that the films with cer tain thick ness is uniform，and solvent，sol concentration，applied volt age，elec- trophoresis time，coating times and doped ions etc take an ex tent effect on the quality of the films and its photo-catalytic degrada tion.
